摘要/Abstract

摘要： 本文设计合成了一系列具有共轭结构的二茂铁咪唑衍生物,它们在质子的作用下呈现显著的光谱、核磁及电化学响应.在中性(或碱性)环境中,其氧化还原波处于低电位,表现为分子“关”的状态;在酸性环境中,其氧化还原波处于高电位,表现为分子"开"的状态;通过酸碱的调控作用其氧化还原波可以在高、低电位之间可逆转换,能够作为一类新型的电化学开关器件.

关键词: 二茂铁咪唑衍生物, 电化学开关, 酸碱调控

Abstract: A series of ferrocenyl imidazole derivatives were obtained via Radziszewski synthesis,which exhibit an intriguing spectroscopic and electrochemical response upon protonation.In neutral or basic solution,the compounds exhibit low redox potentials representing an OFF state;while in acidic solution,the protonized compounds exhibit high redox potentials representing an ON state;these processes are reversible and can be controlled via the adjustment of acid/base.All these features made these ferrocenyl molecules the promising electrochemical switches.

Key words: ferrocenyl imidazole derivatives, electrochemical switch, acid/base control
